SOLAR CONTROLLER
P/No. SC110
12 VOLT
4 STAGE CHARGING

WARNINGS – IMPORTANT PLEASE READ
• SC110 is designed for indoor use only
• Use SC008 or SC015 for outdoor applications
• Do not disassemble the controller. Take to a qualified person if the unit requires repairing.
• Lead acid batteries can be dangerous. Ensure no sparks or flames are present when working
near batteries
• Eye protection should always be used. Never short circuit the battery
• Given sufficient light solar panels always generate energy even when they are disconnected.
• Accidental ‘shorting’ of the terminals or wiring can result in sparks causing personal injury or a fire
hazard. We recommend that you cover up the panel(s) with some sort of soft cloth so you can block
all incoming light during the installation. This will ensure that no damage is caused to the Solar
Panel or Battery if the wires are accidentally short circuited
• Always install a battery fuse on each circuit including the solar controller
MOUNTING THE DEVICE
The Solar Controller is mounted as below
The quickest and easiest way to mount the unit is to use the two plastic spacers and self tapping
screws supplied and mount the unit to a flat surface.

FEATURES
• 4 Stage charging ensures the battery is charged to the optimum level
• Advanced MCU control pulse width modulated (PWM) technology, high efficiency operation
• Programmable for Gel, AGM, Conventional lead-acid (WET) and Calcium Batteries
• Built in regulator to prevent your battery from being overcharged. Overcharging occurs when the
charge voltage is unregulated. This can result in premature battery failure
• In built regulator prevents your battery from being under charged, in the solar energy field, battery
undercharge often occurs, especially on some conventional Lead Acid or Calcium batteries; the unit
provides an automatic equalization feature for deeply drained conventional Lead Acid battery or
Calcium battery, as well as provides a cycling automatic equalizing feature every 28 days
• These solar controllers can be connected to the battery permanently to keep the battery fully
charged by using a process called “floating”. This means the controller will stop charging when the
battery is full and will automatically start charging the battery as required. This process will also
reduce water loss and help prevent the battery from ‘drying out’
• Protects your battery from discharge at night. Under low light or no light conditions the solar panel
voltage could be less than the battery voltage. The unit contains a special circuit which prevents
current flowing back from the battery and into the solar panel
• Colored LED’s to easily indicate the operational status and battery conditions
• Digital LCD to directly display battery voltage, charging current, charging capacity (Amp hour),
battery types, full charge and faulty codes
• Provides external battery temperature sensor (Optional)
• Multi charging protections against reverse polarity, short circuit, over temperature, over voltage, etc.
• Surface Mount or Flush Panel Mount options
• Conformal-coating circuit boards and plated terminals protect the unit in hostile environments
For use with 12Volt Solar Panel Only. Suitable for solar panels up to
120 Watts (SC110).

WIRING CONNECTIONS
To protect the battery and solar panel, it is recommended that you place an inline fuse on the
positive wire of both the ‘Solar’ and ‘Battery’ circuits. A 20A fuse is required and should be installed
as close to the battery/solar panel as possible.
The Solar Controller has 4 terminals which are clearly marked ‘Solar’ and ‘Battery’.
There is a (12V) and earth (GND) terminal for each circuit.
Refer to the wiring diagram below.
1. Using the string wires, tightly screw the wires to the “Solar” terminal on the back of the
controller and connect to the solar panel as shown above in Fig 3.
2. Using the string wires, tightly screw the wires to the “Battery” terminal on the back of the
controller and connect to the battery as shown above in Fig 3.
When the connections are completed, the Solar Controller will start working automatically.
OPERATION – LCD DISPLAY
Please check your battery manufacturer’s specifications to select correct battery type. The unit
provides 4 battery types for selections: Gel, AGM, WET (conventional lead acid), and Calcium.
Correct Wire Size:
Please refer to the wire size chart below to
determine the minimum size wire needed
for each connection. This will also ensure
you get the best performance out of
your solar regulator.

Press BATTERY TYPE button and hold for 3 seconds to go into your battery type selection mode,
the battery type you select will be shown on the LCD meter, the default setting is AGM Battery;
the controller will automatically memorize your battery type setting.
Caution: Incorrect battery type setting may damage your battery.
When the controller powers on, the unit will run ‘self-qualify’ mode and automatically show
below items on LCD before going into charging process.
Self-test starts, digital meter segments test
Software version test
Rated voltage and current test
After going into the charging process, the LCD displays the charging status as below:
Press VOLT/AMP button in sequence, the LCD will display in turn with Battery Voltage,
Charging Current and Charged capacity (Amp-hour).
Display in the day time:
Display during the night:
Display when the battery is fully charged
Press VOLT / AMP button in sequence, the LCD will display in turn with Battery Voltage,
Charging Current, if you do not press the button, the LCD will alternatively display the FUL
and VOLT or FUL and AMP every 2 seconds.
CHARGING STAGES
The VOLT / AMP button can be changed at any time during charging process.
The LCD also can be treated as an independent voltage meter. A voltage less than 11.5V Volts
indicates that the battery is discharged and needs re-charging.
Soft Charge (Stage 1a) – When batteries suffer an over-discharge, the controller will softly
ramp the battery voltage up to 10V.
Bulk Charge (Stage 1b) – Maximum current charging until batteries rise to Absorption level.

Absorption Charge (Stage 2) – Constant voltage charging and battery is over 85%.
Equalization Charge* (Stage 3) – Only for WET battery or Calcium battery type, when the
battery is deeply drained below 10V, it will automatically run this stage to bring the internal cells
as an equal states and fully complement the loss of capacity (Gel and AGM battery do not run
Equalization charge).
Float Charge (Stage 4) – When the battery is fully charged it is maintained at a safe level.
A fully charged battery has a voltage of 13.6 Volts.

OPTIONAL EXTERNAL DEVICE
The controller provides an optional devices (not included P/No. SC1TMP).
Optional external Battery temperature sensor:
As an option, the unit provides a port to connect the external battery temperature sensor;
If the external battery temperature sensor is connected, the unit will optimize the charging
performance subjected to the battery temperature detected and also provide the battery over
temperature protection, in some case, if battery over temperature occurs, the controller will
automatically stop charging.
